Abstract:
... The goal of this study is to experimentally assess the role of vertical sinking and degradation processes of persistent organic pollutants (POPs) in a subtropical water column. This was done by measuring the concentrations of selected typical organochlorine pesticides, including hexachlorocyclohexanes (HCHs), hexachlorobenzene (HCB), dichlorodiphenyltrichloroethanes (DDTs), trans-chlordane (TC), a ...

Abstract:
... The present study evaluated the effects of a biodegradable chelant, S,S-ethylenediaminedisuccinic acid (EDDS), on enzyme activities and microbial community composition in copper (Cu)-contaminated soils, planted with either corn or beans. Results showed that the application of EDDS did not affect urease and acid phosphatase activities in the soil, but greatly reduced catalase and saccharase activit ...
